When Ziva and Tony find the silver Jetta in the parking garage, there is a shot of the rear of the Jetta, and the Volkswagon emblem is clearly missing. Moments later when Ziva picks the lock of the trunk of the Jetta the VW emblem is clearly visible.
When Abby is talking to Gibbs in her lab there is a brief shot where the spider web tattoo is on the wrong side of her neck.
The cell phone on the interrogation table switches positions between shots.
While explaining to Gibbs in her lab how much time the abducted Navy Officer has to survive in the trunk of a car, Abby's spiderweb tattoo switches from the left side of her neck to the right side. It's supposed to be on the left side. The film may have been reversed during editing.
There are several close ups of maps showing Baltimore and New York.... But Baltimore is listed as state MA. This is incorrect, as the abbreviation for Maryland is actually MD.
Habitat for Humanity is a Christian-based organization, and does not run on Sundays. The cast clearly sets the date as a Sunday and Abby explicitly states she was volunteering at Habitat that morning.
Ziva is shown picking the lock on the passenger side of the VW Jetta. VW Jetta's of that year don't have key holes on the passenger side.
When Ziva picks the trunk lock of the Volkswagen, both front doors still need to be picked to open. In reality turning the key cylinder in the trunk will cause all doors to unlock.
When Tony and Ziva first find the VW Jetta, there is no "VW" decal on the trunk. Later, when Tony is popping the trunk, the "VW" decal is clearly visible.
As Tony and Ziva leave the Squad Room at the beginning of the episode (Around 4:32), A crew member can be seen attempting to hide beside Tony's desk in the back of shot when Ziva turns to wave at Abby.
In the beginning of the episode, Ziva says that Gibbs rule no. 3 is "Don't be unreachable". But in episode 1, seas. 1, "Yankee White" Gibbs tells Kate that rule no. 3 is "Don't believe what you're told. Double check."
When Tony is putting on his rubber glove in Lt. Cmdr. Wilkerson's apartment you can briefly see the middle finger of the glove is empty and flops behind his hand and that his last 2 fingers are in the same finger of the glove.
When the supervisor is explaining what the naval officer was working on, he says she's pretending to be a 14 yo girl. When they show the chat session it clearly says, "13 F DC". He repeats the age 14 near the end of the show again also.
When the teenage boys are talking about Ziva, they compare her to Salma Hayek, and the way the latter used knives in Desperado (1995). Hayek doesn't use knives in that film, but rather its sequel, Once Upon a Time in Mexico (2003). This could be intentional, to depict the attention span and memory of the character(s).
